CLEARER-ROLL FOR CARD ING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 603,044, dated April 26, 1898. Application filed $eptemher 30,1897. Serial No.653,594=. (Nomodeh) To a, whom it may concern.-

Be it known that I, EPHRAIM E. ORRELL, of Ware, in the county of Hampshire and State of Massachusetts, have invented a new and useful Improvement in Glearer- Rolls for Carding-lllachines; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to a device for removing the lint and dust which in the operation of a revolving-flat carding-machine collect on the supporting-bars of the topflats;

and it consists in a roll or bar provided with longitudinal ribs, whereby the surfaces of the supporting bars of the revolving flats are swept and the lint and dust removed, as will be more fully set forth hereinafter.

In the class of carding-machines known in the art as revolving-flat cards the centrifugal force of the main carding-cylinder drives some of the lint, leaf, and dust of the cotton or other fiber operated upon through the joints between the flats. The lint and dust accumulate on the supporting-bars of the flats and have to be from time to time removed. The flats consist of a bar of practically T-shaped section,the transverse surface of which is covered with card-clothing. When in the operative position,the transverse card-clothed surface is in close proximity to the main carding-cylinder, and the cross-section is of the form of an in verted capital letter T, the stem of the T forming the strengthening-rib of the flat.

To remove the lint, dust, and other impurities from the surfaces of these T-shapedsupporting-bars of the flats, the clearer device must wipe every part of the surface,and therefore must adapt itself automatically to the surfaces.

One object of this invention is to so construct a clearer that every part of the supporting-bars of the revolving flats will be wiped by the same.

Another object of this invention is to so construct arevolving-top-flat clearer that the same may be readily removed and replaced.

Another object of the invention is to produce a clearer for revolviug-top-flat cards from which the lint and dust can be more readily removed at a low cost.

I have illustrated in the drawings a clearer provided with four ribs, having found in practice that this form performs the work satis factorily, although a clearer with three ribs will operate to remove the lint and dust fairly well.

Figure l is a side view, partly in section, showing a part of a revolving-topflat card ing-machine sufficient to illustrate the operation of my improved clearer-roll. Fig. 2 is an end view of some of the top-flats, showing the clearer-roll in another position. Fig. 3 is an end view of some of the top-flats, showing the clearer-roll in a third position. Fig. at is a perspective view of my improved clearerroll.

Similar numerals of reference indicate corresponding parts in all the figures.

In the drawings the numeral 5 indicates the flats; 6, the chain by which the flats are connected; 7, a disk secured near each end of the shaft 8, on which sprocket-wheels (not shown) are secured which engage with the chain 6. The shaft 8 is supported at each end in an adjustable bracket 9, secured to the side frame 10 of the carding-machine. The clearer-roll 11 has the radial ribs 12. In the preferred form I use four ribs 12, as shown in the drawings, of awidth equal to the depth of the rib on the back of the flat; but I do not wish to confine myself to any particular number of ribs, as with a larger roller more than four ribs may be used.

The clearer-roller may be made of any suitable material. In practice I flnd that a Wooden roller provided with radial ribs covered with felt or clearer-cloth will roll and tumble over and on the backs of the flats and wipe all the surfaces, and thatit will collect the lint, fiber, dust, and leaf and mat the same, so that when the clearer-roll is withdrawn the matted lint and dust can be quickly stripped off.

My improved clearer-roll is placed by the operative into the lower end of the endless chain of revolving flats. It is not connected with any part of the flats or their support, but allowed to freely tumble and roll over the back of the flats. It is extremely cheap and simple in construction, readily inserted and removed, and can be used in any revolving-flat card by simply inserting the clearer-roll. By lifting the accumulated lint at one end the Whole matted covering can be quickly stripped off from the clearer-roll.

While in the preferred form my clearerroll is disconnected from any part of the machine, the clearer-roll may be provided with a rod on each end and held by these rods in suitable bearings, so that the forward-moving flats Will turn the clearer-roll and the radial ribs will Wipe the surfaces.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 1. The combination with the top-flats of a revolving-flat carding-machine, of a clearerroll provided with radial ribs supported on the flats, disconnected from any part of the machine and free to tumble over the moving flats, Whereby the rotation of the clearer-roll brings the radial ribs in contact with the surhand.
